Environmental Vadose Zone Hydrology: Physical and Biogeochemical Processes Across Scales
Session ID#: 157622
Session Description:
The vadose zone provides a number of functions in the Earth’s critical zone and sustains other ecosystems. A wide range of critically important environmental and hydrological phenomena such as recharge, evapotranspiration, transport of species (e.g., emergent contaminants), and biogeochemical cycles occur in the vadose zone. However, the spatial and temporal dynamics of many vadose zone processes are still poorly understood due to the random and structural heterogeneities that exist across scales in both time and space, the complexities and non-linearities that occur within and between (coupling) processes, and the difficulties associated with monitoring and quantifying these heterogeneities and their impact on abiotic and biotic processes. We solicit abstracts that address the above-mentioned challenges. Topics of interest include, but are not limited to—unsaturated and multiphase flow and transport, preferential flow, novel parameterization approaches, climate change-induced processes and new hydrologic regimes, bioremediation and biomineralization, and measurement techniques that combine geophysical approaches with hydrological modeling—as applicable to the vadose zone.
